Lightstep throwing many deprecation warnings

[EdLeafe]

Recently our Python-based project upgraded a lot of our dependencies, including lightstep, protobuf, and grpcio. Since then when we run our unit tests, we see several warning messages from lightstep like these:

.tox/py39-unit/lib/python3.9/site-packages/lightstep/lightstep_carrier_pb2.py:18

Note: Create unlinked descriptors is going to go away. Please use get/find descriptors from generated code or query the descriptor_pool.

The tests continue to pass, but I wanted to a) be sure you are aware of these deprecations, and b) was curious about any plans to remediate them.
